/prog/ - ``GNU/Compatibility''

So I'm trying to load these jpegs natively with that Windows Imaging Component. What I'm getting is undefined reference to _WICConvertBitmapSource@12, and there's no libwindowscodecs.a. Now I make a wincodec.def file like this:

LIBRARY WindowsCodecs.dll

EXPORTS

    WICConvertBitmapSource@12

Then I do dlltool -d wincodec.def -l libwindowscodecs.a and link against this one. Guess what? I'm getting the same error.

But wait, there's more. I've got that gendef tool (because dlltool just threw ``no symbols'') and generated a def file. gcc actually linked that crap, but when I run my program, this guy pops out:
The procedure entry point WICConvertBitmapSource@12 could not be located in the dynamic link library WindowsCodecs.dll.

That's not the only WinAPI function I can't link against, there're some more. And I haven't even told about ``complete'' w32api headers, which I have to constantly update. Now tell me /prog/, how can I fucking make a library which would work fine with gcc? Maybe installing that Windows SDK?

You wouldn't have had this problem if you used Perl 6 on ~~BeOS~~ Haiku

Help please! Despite the ironic tone of the post, the problem actually exists, and I have no idea what to do.

Can't you just use a regular jpeg library?

Why not just the Independent JPEG Group stuff?

If libjpeg is good enough for them, its good enough for you.

No, guys, you didn't get me. I'm loading other formats too, and I've no desire to use that awful libpng API. (You should also know one doesn't simply compile a library on Windows).

What I'm actually asking is how the hell you make import libraries for system dlls on MinGW?

That was very helpful of you, /prog/. The answer is: RTFM and use --kill-at flag. This is how I make homebrew import libraries now:

gendef C:\Windows\System32\WindowsCodecs.dll

dlltool --kill-at -D WindowsCodecs.dll -d WindowsCodecs.def -l libwindowscodecs.a
